The FB1100 Flow Computer includes a single type of termination board that uses 6-connector pluggable terminal blocks. The FB1200 Flow Computer supports the same termination board and blocks. In addition, if the FB1200 Flow Computer is purchased with the 6-channel expansion I/O board, it uses a different termination board with 8 (or in one case 9) connector pluggable terminal blocks.
